Due to the growing concern of aggravated environmental problems (air pollution, global warming, etc.) and Li resources, Na‐ion batteries have received significant attention as a promising alternative. Many electrode materials for Na‐ion batteries have been reported in the past, especially over the past five years. However, most of these materials have a single crystalline structure and exhibit a limited electrochemical performance. Recently, some electrode materials with composite structures have been reported for both Li‐ion and Na‐ion batteries and have attracted attention because of their enhanced comprehensive electrochemical performance. Herein, a detailed discussion on the development of these composite‐structure materials for Na‐ion batteries is conducted based on the crystalline structure. The structure design, identification, and adjustment of these materials are thoroughly discussed. Furthermore, the future outlook based on a mechanism analysis and a new electrode‐material structure system is also introduced in this work, by reviewing previous important studies on composite‐structure materials.

钠离子电池复合结构材料

由于日益严重的环境问题（空气污染，全球变暖等）和锂资源的关注，钠离子电池作为一种有前途的替代方案受到了广泛的关注。过去，尤其是在过去的五年中，已经报道了许多用于Na离子电池的电极材料。然而，这些材料中的大多数具有单晶结构并且表现出有限的电化学性能。近来，已经报道了用于锂离子和钠离子电池的具有复合结构的一些电极材料，并且由于它们增强的综合电化学性能而引起了人们的关注。在此，基于晶体结构对这些用于钠离子电池的复合结构材料的开发进行了详细的讨论。结构设计，识别并详细讨论了这些材料的调整。此外，通过回顾先前对复合结构材料的重要研究，在这项工作中还介绍了基于机理分析和新的电极材料结构系统的未来前景。
